基于水文连通分析的江湖关系研究进展

水文连通度具有自然和社会双重属性，但基于水文连通分析的江湖关系的综合论述尚不足，为此首先阐述了水文连通度的定义和分类；其次，归纳了横向水文连通度量化方法，并讨论了基于横向水文连通分析的江湖关系定义；最后，以洞庭湖为例，引出在人类活动干扰下，江湖关系逐渐发生变化这个问题，针对这一问题对未来进行展望，尝试建立江湖水沙变化、江湖关系演变在人为因素和气候变化综合因素影响下的响应模型，提出了可维持生态健康的工程措施，以期加强江湖的治理。

Research Progress on the River-Lake Relation Based on Hydrological Connectivity Analysis

Hydrological connectivity possesses both natural and social attributes, but comprehensive reviews are scare about this issue. This paper firstly illustrates the definition and classification of hydrological connectivity. Secondly, the quantitative methods of lateral hydrological connectivity are generalized. Finally, the Dongting Lake is taken as an example to introduce the gradual changes of river-lake relation due to human disturbances. Concerning on this problem, the paper explores some measures that can be taken in the future. It is suggested to build a response model which considers the comprehensive influence of water and sediment changes, and the evolution of river-lake relation under human disturbances and climate change. In addition, effective engineering methods should be designed to enhance the ecological health and strengthen the management of rivers and lakes.
